Vivaspin® 15R has all the unique features of the Sartorius centrifugal concentrators, including a patented vertical twin membrane and a dead stop. Vivaspin® 15R targets the volume segment of 2 to 15mL with the Hydrosart® regenerated cellulose membrane. This membrane is ideal when extremely high recovery rate and very low adsorption is required, for example in applications such as concentration and desalting of immunoglobulin fractions.
- Highest recovery at low absorption (95-98%)
- Extremely short concentration time (30-fold in 15 min.)
- Very small holdup volume (< 20µL)
- Crystal clear housing and volume graduations
- Vertical twin membrane for ultra-fast concentration
- Safe sample concentration due to dead-stop volume
